Application nled August 29, 1917. Serial No. MotM- To all whom it mayconcern.:

Be it known that l[, GEORGE Horrn, a citizen of the United States, and aresident of the town of Charlotte, county of Living` ston, and `State ofIllinois, have invented certain new and useful improvements in Seed-Planting Machines, of which the following is a specification.

My invention relates to improvements in seed planting machines,especially designed for use inplanting corn, and has for its object theproduction of a device of this character, which will be of durable andeconomical construction and efficient in use.

The invention consists in the combinations and arrangements of partshereinafter de-` scribed and claimed. s

rfhe invention will be best understood by reference to the accompanyingdrawings forming a part of this specication, and in which, t y

` Figure 1, `an enlarged vertical section taken through dischargemechanism employed in the construction. y

Fig. 2, a still further enlarged vertical section taken through thelower end vof the discharge hopper.

Fig; 3 a horizontal section of thedischarge mechanism, and

Fig. 4:,` a section taken on line `5--5 of rlfhe preferred form ofconstruction,` as illustrated in the drawings, comprises a seeddepositing mechanism comprising a hopper 22, which is provided at itsupper end with a hinged cover 23. rlFhe lowerend `of each hopper ishinged at 24 totheupper end of a support 25, which is supported-by theframe 13. A suitable locking device 26 cooperates with each hopper 22 tolock the same against pivotal movement relative to the correspondingsupporting member 25. Arranged in each of the members 25 is a seeddischarge tube 27, the arrangement being such that the open upper end ofthe tube 27 is arranged out of alinement with the discharge opening 28of the corresponding hopper.

Arranged at the lower end of each hopper is a shiftable plate 29, havingan opening 30 therein adapted, upon shifting of said plate, to bebrought into successive. registration with the corresponding opening 28and the upper end of discharge pipe 27. The arrangement is such that inthe operation of the machine, when the hopper is lled with seed, as theplate 29 is brought to a position withthe opening 30 therein regisutering with opening 28, a number of seeds will drop into said opening30, and, upon shifting of the plate, will be carried thereby to anddischarged into wpipe 27. Hence,` with this arrangement, uponeachcomplete reciprocation of the plate 29, a number of seeds will bewithdrawn from the corresponding hopper and conveyed and dropped intothe corresponding pipe 27 In order to depress the upwardly project4 ing`ends of any grains or seeds which might become so arranged in theopening 30, l provide an upwardly yieldable spring held scraper memberor leaf 30 arranged to con ing with each plate 29 is a spring pressedVplunger 35 adapted, when the opening 39 in the plate reaches a positionin registration with the corresponding pipe 27, to enter said openingand push -any seeds which may lodge in said opening downwardly into thepipe 27. An edective means is thus provided for preventing clogging ofthe plates 29, which might otherwise occur. The rearward side ofeachplunger 35 is beveled as at 36 in order to effect automatically theraising of the same by the corresponding plate 29 when the latter ismoved forwardly.

Carried by each plate 29 is a leaf spring 37 adapted upon rearwardshifting of the former to register with the lower end of thecorresponding hopper and thus insure the prevention of any dischargetherefrom when the plate is moved rearwardly.

Coperating with the lower end of each of the discharge pipes 27 is aclosure 38 fulcrumed at 39 in the corresponding member 25. With eachclosure 38 coperates a spring 40 for normally holdin the same in closingposition. Rocking o the closures 38 to open position is effected bymeans of a rod 41 which extends across the machine through arcuate slotst2, formed in adjacent sides. of the members 25, the ends of said rodresting in the bifurcated upper ends of the Shanks of closures;.38.rThe-.rod .41.is..

carried at the outer .ends of the rocker arms 43 which are Xed to anoscillatory shaftlll,

the arrangement being such, as is apparent,

thatoscillation of said.y shaft WillV effect actuation or movementof.-,the closuresl 38.

It is of course apparent that the distance betweenmthe vhillsfof seedsplanted .Will `be determined by `the. .length of the vchain andby,..varying.the length., of .the latter, .the
